Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and fastening challenges in precision assemblies. The 3/4" shoulder length with controlled tolerances ensures accurate positioning of components like gears, pulleys, and linkages, minimizing misalignment and reducing wear in machinery. The 8-32 UNC coarse thread with Class 3A fit provides a secure, tight connection that resists loosening under vibration, common in automotive, aerospace, and industrial equipment. Made from corrosion-resistant stainless steel, it withstands exposure to moisture and chemicals, while the hex drive and knurled head facilitate quick installation in confined spaces. Ideal for applications requiring high strength and reliability, this screw enhances operational efficiency and reduces maintenance needs.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with an 8-32 thread size and Class 3A thread fit for precise dimensional accuracy. The shoulder diameter and length maintain tight tolerances (e.g., shoulder diameter: -0.004" to -0.002", shoulder length: -0.005" to 0.005") to ensure consistent performance. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industries.
